300CE seat problems
Neither of the seat backs will lock on my '89 300CE. I've done some research to try and determine what might be the problem. Most of the problems I researched were particular to the W123 chassis. Is the system similar on the W124? I pulled the back left seat cushion and looked at a small valve with several baby blue vacuum lines exiting from it and travelling to the front seat. The lines all look to be in very good condition and were snug on this valve. I noticed that when I open and close the driver's door this small valve clicks when the ignition is turned off. I'm thinking that perhaps one of the vacuum elements underneath the front seats is leaking. Where should I test to see if they are defective? The central locking is functioning perfectly fine. Is the locking actuation for the seats on a different line than the other vacuum components?
My second problem is with the driver's side memory seat. Every so often the seat reconfigures itself to a different position. It usually adjusts itself just after I have turned the ignition on. The headrest and steering column will also move themselves on their own. I have pulled the seat controls off to clean the connections as well as disconnected the battery to clear the stored memories but the problem persists. I did a search and found very little information about a problem similar to this. Is it the seat switch on the door that houses the memory unit that is likely the culprit? Sometimes when I open the passenger side door the seat will adjust itself even though the ignition is off. What do I need to look for to correct this gremlin?
